We present a numerical study on the rheology of semi-dilute and concentrated filament suspensions of different bending stiffness and Reynolds number, with the immersed boundary method used to couple the fluid and solid. The filaments are considered as one-dimensional inextensible slender bodies with fixed aspect ratio, obeying the Euler–Bernoulli beam equation. To understand the global suspension behaviour we relate it to the filament microstructure, deformation and elastic energy and examine… 

Rheology of concentrated suspension of fibers with load dependent friction coefficient

We numerically investigate the effects of fiber aspect ratio, roughness, flexibility, and flow inertia on the rheology of concentrated suspensions. We perform direct numerical simulations modeling

Numerical study of suspensions of nucleated capsules at finite inertia

We study the rheology of suspensions of capsules with a rigid nucleus at negligible and finite flow inertia by means of numerical simulations. The capsule membrane is modeled as a thin Neo-Hookean

Suspensions of deformable particles in Poiseuille flows at finite inertia

We analyze a suspension of deformable particles in a pressure-driven flow. The suspension is composed of neutrally buoyant initially spherical particles and a Newtonian carrier fluid, and the flow is

Abstract The present work investigates the mechanical behaviour of finite-size, elastic and inertial fibres freely moving in a homogeneous and isotropic turbulent flow at moderate Reynolds number.

Turbulence in a network of rigid fibers

The effect of a network of fixed rigid fibers on fluid flow is investigated by means of three-dimensional direct numerical simulations using an immersed boundary method for the fluid-structure

Signatures of elastoviscous buckling in the dilute rheology of stiff polymers

Abstract As a stiff polymer tumbles in shear flow, it experiences compressive viscous forces that can cause it to buckle and undergo a sequence of morphological transitions with increasing flow

A free flexible flap in channel flow

Abstract Fine fibre immersed in different flows is ubiquitous. For a fibre in shear flows, most motion modes appear in the flow-gradient plane. Here the two-dimensional behaviours of an individual

Dispersed Fibers Change the Classical Energy Budget of Turbulence via Nonlocal Transfer.

The backreaction of dispersed rigid fibers to turbulence is analyzed by means of a state-of-the-art fully coupled immersed boundary method and provides a link between two apparently separated realms: the one of porous media and theOne of suspension dynamics.



A numerical study of the effect of fibre stiffness on the rheology of sheared flexible fibre suspensions

A recently developed particle-level numerical method is used to simulate flexible fibre suspensions in Newtonian simple shear flow. In this method, the flow is computed on a fixed regular ‘lattice’

Numerical simulations of elastic capsules with nucleus in shear flow

The shear-induced deformation of a capsule with a stiff nucleus, a model of eukaryotic cells, is studied numerically and the results obtained modelling the nucleus as an inner stiffer membrane with those obtained using a rigid particle are compared.

Simulation of semidilute suspensions of non-Brownian fibers in shear flow.

The simulated viscosity determined directly from shear stresses was in fair agreement with experimental data found in the literature, and the first normal stress difference was found to be proportional to the square of the volume concentration of fibers in the semidilute regime.
